Notes to Kilroy -
Me (asking the question): What in the world did (do) people without permanent housing do during extended periods of high wind?
Answer: They endure(d) the best they could/can with whatever shelter they could/can find or construct. Caves are great, unless they are already occupied by vicious critters; valleys or ravines can be good, until the flood waters show up; partially fallen tree trunks can work - especially with a tarp thrown over, unless whatever is holding them up is not really secured. I guess Rob and Lonnie may have to endure a big windstorm, so we can find out ...
